Proactive IR Tools

Proactive Charts

One custom element, <proactive-charts>, loads historical price + volume and draws with Apache ECharts, TradingView Lightweight Charts, Highcharts Stock, or amCharts 5 — pick via chart-engine.

All live charts below use the same Morningstar-style feed: provider="morningstar", exchange="6" (Morningstar only), symbol="III", currency="CA$". Set VITE_MORNINGSTAR_ENDPOINT and VITE_MORNINGSTAR_TOKEN in .env (see .env.example).

Live examples

Featured first: the IR console (chrome="console"), then Apache ECharts and TradingView Lightweight Charts. Highcharts and amCharts require paid licenses — see Commercial Solutions. Morningstar demos share exchange="6" / symbol="III". Expand HTML snippet to copy markup.

chrome="console" · chart-engine="echarts"

IR-style chart console

Dual-axis price + volume, markers, overlays, range presets, from/to, export (PNG / JPEG / SVG / CSV / PDF), and reset. Layout is tunable via console-panels, console-toolbar, console-actions, console-ranges, and console-reset.
